Chennai sets Sept 30 deadline to clear Cooum debris

The Greater Chennai Corporation has set a firm deadline of September 30 to complete the removal of debris and silt from the Cooum river. The move is part of a broader effort to improve the river's flow and reduce the risk of inundation in low-lying areas when the northeast monsoon arrives.

Officials say the clean-up will target accumulated garbage, construction waste, and thick silt that have narrowed the river over the years. The Corporation has been under pressure from residents and environmental groups to act, especially after past floods exposed the river's poor carrying capacity.

Why the Cooum needs urgent attention

The Cooum, which runs through the heart of Chennai, has long been a dumping ground for sewage and solid waste. Its banks are lined with encroachments, and the river's mouth often gets blocked by sandbars. This combination makes it prone to overflowing during heavy rain.

Last year's monsoon, though not extreme, saw waterlogging in several neighbourhoods near the river. Civic officials admit that a cleaner channel would help drain stormwater faster and prevent such disruptions.

Scope of the work

The Corporation has not yet published the exact quantity of silt and debris to be excavated. But sources indicate that the operation will cover the river's full stretch within the city limits, including stretches where vegetation has taken root on accumulated sediment.

Heavy machinery, including excavators and trucks, will be deployed at several points simultaneously. The removed material will be transported to designated dumping yards, and the Corporation has said it will ensure that no debris is dumped back into the waterway.

The deadline is tight, given that the northeast monsoon typically sets in around mid-October. Any delay could leave the river unprepared for the season's rains, which often arrive in short, intense spells.

Past efforts and challenges

This is not the first time the Corporation has announced a clean-up of the Cooum. Similar drives have been launched in previous years, but they have often been stalled by funding constraints, lack of coordination between agencies, and the sheer volume of waste.

Environmental activists have pointed out that desilting alone is not enough. They argue that stopping untreated sewage and industrial effluents from entering the river is essential for a lasting fix. The Corporation has acknowledged these concerns but says its immediate priority is to ensure the river does not become a flood hazard.

What residents can expect

Residents living along the Cooum may notice increased activity on the riverbanks over the coming weeks. The Corporation has appealed for cooperation, especially from those who have been using the river as a waste dump.

It has also warned that encroachments along the banks will be removed as part of the drive. However, officials have not clarified whether rehabilitation will be provided for those displaced.

The next few weeks will show whether the Corporation can stick to its schedule. For now, the September 30 deadline is a clear signal that the city is serious about preparing for the monsoon, but the real test will be in the execution.
